To ALL WHOM I'r MAY CONCERN: i

Be it known thatvI, MILTON ErInILLIrs, oi' Lena, in the county of Stephenson, and State of Illinois, have rinvented certain new and useful Improvements in. Grain-Threshers and Separator-s, of which the following is a.

full, clear, and exact description, reference being had tothe accompanying drawings, which make part of this specication, and in which- Figure 1 represents a side elevation,

Figure plan view, vand A Figure 3 a vertical longitudinal section through my improved machine at the'line :c x of iigfjl.v

The invention herein claimed consists in certain novel devices, by means of which the same machine may be used for threshing, separating," and cleaning grain, and for hulling clover or other seed.

In the accompanying drawings, which exemplify one convenient arrangement of mechanism for carrying` out the objects of my invention, I have shown a stout fra1ne.zl, of suitable construction to receivcthe nischenism.4 An inclined driving-shaft, B, driven from ahorse-power (or other suitable motor) is mounted centrally in the frame in suitable bearings. A gear-wheel, b, on this shaft drives a corresponding pinion, c, on a cross-shaft,-

c, carrying a spur-wheel, C C1, on each end, outside the fram-e. These wheels drive small spur-pinions, d dl, on the shaft of the threshing-cylinder D, provided with a suitablcconcavo, D1. Behind the cylinder a series of`stationary rods or bars, e, is arranged lengthwise ofthe frame, and parallel to each other. Aseries of parallel rotating shafts or rakes, E, is arranged transversely beneath these bars, and provided with curved rods or beaters e, which rotate between the slats and'carry thestraw back to' the straw-carrier. These -rods have cranks, e2, on their ends, and are driven by'a crank and pitma-n,.e3, on each of the'whieels C CL. A shaking-screen, F, is sus. peuded beneath these rotating shafts or rakes 'E byparallel rods f, and vibrated longitudinally by means of a. pitxfna'mf, connectdwith an. eccentric on a transverse shaft, G, driven by a crank and pitman -from each of' Y the wheels C Gl. Another eccentric on this shaftvibrates ashaking-shoe, I-I, `suspended beneath the screen. The'return-hoard 71. 'on the rear end of the shoe'is inclined'forward, so as to leave a space, L, between the board and shoe for the blast. A trough,f,'on the rear end of the screen, leads to an elevator, I, which extends forward to a point above the threshing-cylinder, for a purpose hereinafter shown.Vv A troughfh, leads downward and forward from the rear end of the shoe to a revolving screen, J, covered with screens 1 2 3, of varying {ineness, snd rotated ,from the main ear-wheel b b means of an idle-wheel, B1, carin into a s ur-wheel, j, onthe g Y g g P forward end of' the screen-shaft jl. A fan, K, is enclosed in av suitable case, 7c, and driven bygearing from the screen-shaft. The fan is supplied with air through `a longitudinal slit in the bottom of the fan-case, which opening is'closed by a .regulating-"valve, s, turning on a pivot, so that it can be opened tothe desired extent, and'be held by a spring-detent, s, taking into' notches on a wheel, s2, on the valve-pivot." Suitable bins, L, are arranged beneath the revolving screen to receive andkelep separate the different qualities of grain. A hulling-I cylinder, M, and concave or case, m, are arrangedl beneath the threshing-cylinder. The hulling-cylinder is driven from the wheels C Cl by spur-piniozns, m, on each end of its shaft. To prevent the breaking of the hulling-cylinder -or case by stones getting mixed with the clover, I cut away a section from the bottom of .the casing'and replace it by' a cover, mi, held up to its place by springs, m2, which yield when a. rigid obstruction is encountered, and permit it to escape. A bevel-pinion, R, on the screen-shaft jl, drives a pinion, r, on a transf t verse shaft, r1. A bevel-wheel, r2, on the outer end of this shaft, drives a small pinion, n', on a. longitudinal shaft, A bevel-pinion on the front end of this shaft drives a pinion on the shaft of the elevator O, While a pinion, c, drives thefan.l A pinion, p, on the rear end of this shaft, drives a pinion, p, on the shaft of the straw-carrier P, which hns a joint, p, in its middle, (for convenience in' packing for storage or transportation,) t

and is connected with th'emain frame link-rods p3. v

The operation ofthe machine is as follows: When used as a thresher and sepnratoror cleaner, an attendant stands on the front apron or platform ,Q and feeds the bundles into the .threshingcylinder D, which separates the grain from the straw, when both pass back to the revolving rakes E. Asthe rake-teeth successively rise between the slats e they impart a quick jogging backward motion to lthe straw, which motion eectually shakes out the grain, which falls upon the shaking-screen F, which still further separates the chaff from thegrain.`

The latter falls through the'screen upon the shaking-shoe H, and drops from its rear end upon the return-board h, being exposed during its descent to a blast from the fan K which blows oi the chaff. The straw falls from the rakes upon the straw-carrier P, which conveys it away to the stack. The heads and eha' from the screen F and shoe H are also blown upon'the carrier. The sound grain is conducted through trough h to the revolving screen J, by which it is assorted according to size and plumpness, and dropped into the bins L, which are provided with sliding doors, in order that the grain may be readily removed. The revolving screen will also separate grass or other seed from the grain.

' The arrows indicate the direction of the movement of tbe'several parts.

For hulling and cleaning clover-seed, the heads are passed through the threshing-cylinder as before. The seed fall between the boards e, but the bottoin ofthe screen Fis covered with a solid plate or board, so that the seed, instead offalling through, pass into thelelevator I through the trough f2, andare returned to the front of the machine. The seed-pass down the spout 'L' into the hailing-cylinder which consists of a series of spiral vanes or beaters, rasped or roughenedon their outer surfaces, to remove the hulls from the seed. Theseed and hulls pass from the huiling-cylinder through the spout o into the elevator O, which discharges them through a trough, o, upon the shaking-shoe H, whence they fall on the return-board `z, being winnowed in their descent by the blast i from the fan, and are conducted into the bins L through the revolving screens J, as before described. I

The. parts may be thrown into or out of gearing in any proper well-known way, and their construction 1 might be varied to some extent without departing from the spirit of my invention.

What I vclaim as my invention, and desire to secure by Letters Patent, is

1. The combination, as described, with the threshing-cylinderD and stationary slats e, of the rotating rakes E, having their shafts connected at .each endlwith the saine gear-wheels which drive the threshing-cylinder.

' 2. The combination, substantially in the manner described, of the threshing-cylinder D, the parallel sluts e, the rotating rakes E, the longitudinally-vibrating screen F, 'and the shaking-shoe H; with the' fan K, for the purpose set forth.

3. The combination, as described, of the threshing-cylinderl) with the hnlling-cylinder M, whereby both are driven at each end from the same gear-wheels. i

4. The combination, as described, of the spiral rasped surface beatersof the hulling-cylinder M with the yielding concave m.

5. The combination ofthe closed fan-case k with the adjustable regulating-valve s, controlled by the springdetent s2, as set forth. I V

6. The combination, substantially as described, of the threshing-cylinder D, the rotating rakes E, the vihrating-screen F, the shaking-shoe H, and the hulling-cylinder M, whereby they are all driven by the same counter-shaft. y vf 7. The combination, with the huliing-cylinder M,of the vibrating-screen F and elevator I, all arranged andoperating as described.

8. The combination, with the hullingcylinder M, of the elevator O, the shaking-shoe H, the fan K, andthe 'revolving screen J, all arranged and operating as described.

In testimony whereof, I have hereunto subscribed my name.
